This inventioir'relates to wheels, having a i special ring for thebrake, and has for its object to provide a. wheel of this kind which combines great strength and small weight with cheapness of manufacture.

One embodiment of the' invention is illustrated in theaccompanying drawing, representing a wheelcomposed of two wheel halves and made of plate, and Figure l is an elevation of a part of the wheel; Fig. 2

Y a section on line 2-'-2 of Fig. 1 with parts of the wheel brake; andFig. 3 a section on line 3-3 of Fig. 1.

Each of the wheel halves A and B is stamped out of thin plate-and consist of a hub part, :1 spoke part c0nuected therewith,

and a flange (Hand 6 respectively at the limb f of the wheel rim 1*, forms the trend of the wheel, while the inner limb f? servesas brake ring for the wheel brake.
